I'm confused about some issues we've been having with transcoding.
We are using 7960's and 2600 H323 Gateways for PSTN Access. I also have a pair of 6608 blades for transcoding.
When Calls come into the H323 GW's from the PSTN the calls are G711. When the gateway passes the call to Call Manager the codec is negotiated based on the region the IP Phone is in. My 7960's are configured in a G729 region.
Now here is my confusion. Does the transcoder kick in and transcode the call from g711 to g729? Or does the H323 gateway do the transcoding?
Yes I have a codec class configured on my 2600 gateway. So with this in mind, the gateway then takes the g711 stream from the PSTN (PRI) and transcodes it as g729 and directs the packets at the 7960 IP Phone using g729?
Then the only time my transcoder will kick in is when there is a device that doesn't support g729, such as my AS-8 gateway's to my voicemail system.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
